qmake: QT += core
Detailed Description▲
As the generic iterators don't actually instantiate a QVariant on each step, they cannot return a reference to one from operator*(). QVariantRef provides the same functionality as an actual reference to a QVariant would, but is backed by a pointer given as template parameter. The template is implemented for pointers of type QSequentialIterator and QAssociativeIterator.
